Imagine this —
You have a hammer. You use it often, and you put it at your bedside when you go to sleep.
You wake up in the morning, and your first action is to reach over and grab your hammer and whack a few things — the wall, the side of the bed, maybe the floor. You get up and stagger to the kitchen to get the coffee going, and you hit a few more things with the hammer while you wait. And when your blessed coffee is ready you sit on the couch and whack a few things within reach while you sip it.
Eventually your kid wakes up and starts whacking things with his own hammer. You yell at him to put his hammer down and get himself ready.
Somehow you’re finally in the car, driving to work. The hammer sits in the passenger seat. You can get a ticket for using your hammer while driving. But it is a lovely hammer, and you glance at it periodically and think about all the things you can hit with it. At one point — even though you know you shouldn’t — you pick up your hammer and give the dashboard a good smack.
You arrive at work. You sit at your desk and whack a few things to get ready to be productive. Every ten to fifteen minutes you take a break to hit something. Sometimes you only hit things for a couple of minutes. Other times you realize you’ve been wandering around hitting various things for half an hour and you don’t know where the time went.
You spend half your lunch break hitting things.
The afternoon proceeds much as the morning. After work you return home and hit a few things in your car before going in and greeting your family. You all sit down for dinner and whack stuff while you eat, each with your own hammers. After supper you sit on the couch with your partner, and you both whack away at stuff. You don’t talk much, but you are whacking together.
By the way, your hammer service company tells you that you’re eligible for an upgrade — you can trade in your old hammer for a new one. Suddenly your old hammer doesn’t seem quite so nice. But that new one promises unparalleled functionality… you think about this when you sit in bed, holding your hammer.
Now — who is the tool?
